[q] gsm sch-815 - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

I know the p6800 is suppose to be the GSM variant, but I want to know if the i815 carrys GSM bands to work on carries like tmobile vodafone or at&t? Perhaps if it is unlocked? I know my HTC Rezound supports this. Just drop any sim, change the APN, and you're off!
If anyone knows if this tablet can do that, that'd be great!

I don't believe the i815 has a GSM radio.

This is correct. The i815 chipset only supports CDMA + Verizon's LTE.

Using GSM on Telus Touch Pro 2

Hello everyone. I just got my Touch Pro 2 from Telus and got it sim-unlocked. I am using it with Rogers wireless. So far so good. Except that 3G does not work Oh well..

Same thing with T-Mobile TP2 on AT&T network. Compare Rogers and Telus 3G bands. It might be different.
not to sound rude, but is the telus 3g (hspa) network even up yet?

lol yeah I think so. I think its called 1x or something like that. I'm not very familiar with the CDMA phones but they advertise that you can use the phone to surf 3G speeds on their network so I'm pretty sure they have 3G speeds.
Sorry, but i'm using TELUS and the HSPA network won't be up till next year and trust me, Telus speeds now are NOTHING close to 3G.
I'm not sure how they are advertising these 3G speeds but 1x is actually slower than what Telus is currently using which is EVDO.

i dont think thats true at all. i get speeds of up to 2.8mg downlink and 500k up.
ive downloaded while tethering upwards up 300kb/s. you might be in an area with 1x coverage, and not EVDO. PLUS make sure the device you are using isnt just EVDO, it has to be EVDO REV A. (touch pro, diamond, touch pro 2, touch, etc). Hope you get better speeds. CHears
Telus EVDO is not slow. Unfortunately the HDPA network is not up yet but it should be online VERY soon as the Olympics are drawing close and this is the reason why Telus is upgrading the network before Feb. 2010 here in Vancouver.

Where the heck are you located?? I'm using a TP2 with full EV signal and i'm getting 400-600k and that's in the downtown core. And from what telus tells me thats the best they can do till they put the HSPA network up. They said CDMA is only capable of 7-750k max, there is no getting over that. But i'd love to know how your getting 2.8 meg, because technically thats roughly 2100k faster than what telus says we can get.
And Jessie is right Telus has a goal to sell phones during the olympics and they plan to have the HSPA up by then.
Yup I'm pretty sure I saw Telus advertising their high speed somewhere
im using a physical sim-card thingy to allow other sim cards to work in my telus TP2, it works (since it does not give me the regular error and i can see the numbers in it), but how do I stop it from using CDMA and go on GSM only?
Guys
I'm hoping you can help us no CDMA users with this question.
Considering that the CDMA TP2 has both GSM and CDMA radios, can I pop in a GSM SIM CARD and enjoy full GSM coverage including use of Asia and European 3G bands?

Yes you can use it on GSM networks. If you want to use the phone on a SIM other that the company's provided sim you need to sim-unlock it. The 3G will work in Asia and Europe but not in North AMerica because the bands are different and the TP2 supports those of Asia and Europe only (the North American CDMA version).

Go to Phone Settings and select the Network tab then select GSM only instead of Global or CDMA

It is quadband gsm.... works on all continents.... provided it is unlocked or you are paying for global roaming.
hello guys, im going to purchase verizon tp2 cause they say it supports gsm and cheaper than the generic nonbranded version. tmobile's design i dislike. so as im going to use it only with gsm sim, i have such questions, are there any differences in use between gsm and vzw versions except i must select gsm mode? can i flash it with generic tp2 roms?
........
okay, seems to be cdma versions cant be flashed to gsm as it is another model id(rhod400 and rhod500)
so i have one more question, will i be able to use internet on vzw tp2 without any restrictions on its stock rom now, when hardspl have not been released yet?
Just to be sure I understand if I want to buy a TP2 in Canada...
The Telus version will not be able to use GSN (Fido/Rogers) 3G network because the 3G bands are not the same as the TP2 from the United-States and Europe?
If so, would this version of the TP2 work with Fido/Rogers GSM 3g ?

I dont think so. I dont think there's a PRO 2 that supports our North American 3G bands.. At least not yet.. For the question above. Yes it is GSM quadband but not 3G quadband. This is different. It is 3G dualband and supports those of Asia and Europe only. Unfortunately.
That's a good and clear answer! Thx !
No problem. I think when and if AT&T or some North American GSM carrier releases the TP2, then the 3G will definitely work here in NA. Otherwise the current versions only support Asia and Europe.
Another question, can we install a custom ROM on the worldphone telus Touch Pro 2 like the other GSM phones? (I dont think so but I found two opposite answers on this forum).

[Q] ATT nexus s needs to work with tmobile

I currently have a nexus s its the factory unlocked that has att 3g band ( i didn't even know it existed when i bought it) i need to try to get some t mobile 3g/4g speeds out of it is this possible and if so what rom and how i have heard it can be done but no definite answer some one please help
Not possible. Best you'll get is EDGE. Same goes for us with Tmo to get on AT&T

This, it will not work.
That model does not support the UMTS/HSPA bands used by T-Mobile (1700/2100). It supports 850/1900 (used by AT&T and several Canadian carriers).
Changing your ROM will not fix this. Flashing a T-Mobile radio will not fix this either - it's a hardware issue.
As it is quad band GSM you will get 2G service.

Not going to work as others said. Best is to sell, re-buy and cut your losses. Sorry.
That's actually what I thought I guess ill just sell and buy something else, thanks for the clarification guys.
try press menu button and press select radio band in phone information after dial *#*#4636#*#*
change to automatic or other country and wait

you are better off returning it, and buying the proper model for AWS band (1700/2100)

[Q] no 3G Sensation/ATT

Hi all, im very new to XDA & have no knowledge of bandwidths. I just recently bought a HTC Sensation (not sure what model, but it was from a local guy). Had it unlocked so i can use it with my ATT plan. every thing was working fine except i had no data & couldnt send/recieve MMS. When first turned on, there was no APN settings on the phone, so i applied the settings stated in the thread APN settings for unlocked Sensation on ATT by mekajt7 on 09/05/11. Now i have data & MMS is working fine execpt my data is only 2G??
If there's anyone out there with more extensive knowledge regarding this topic, or how to get my phone to pick up 3G?? pleeeeeese leave a reply.
ive spent hours online reading about the bandwidths & ive been getting mixed results.... some said yes, it should work & most said no.
I'm in need of some answers
thanks for reading
the only way an sensation can pick up att 3g signals is if you buy one from canada made for their bell carrier. other then that all you can get is edge. if you want 3g or even better, 4g and be in the usa, you need tmobile
thanks for the reply kpholmes. yea, that's the same thing ive been getting from reading online for 4 hours. do you or anyone else reading know the model number for T-Mo's version vs. Bell's version???
i know it's 710a or 710e. but which is which??

The Z710a is the North American (NAM) version sold by Canadian carriers and it supports the 850/1900/2100 3G bands that AT&T uses.
The Z710e supports the European and T-Mobile 3G bands.

so, T-Mo's is neither of these?? or is it the Z710e??
im just trying to get the model's correctly identified
thanks for the reply
T-mo is the same as european and asian version, it wont work with at&t 3G which is probably what you have. You need to get the canadian sensation from bell or virgin mobile model number z710a. If you look at settings>>about phone>>phone identity, the model number of your phone should be there. If it is z710e, then you are out of luck.
So the Canadian version can use 3G on AT&T? And 4G?

Motorola Xyboard 10.1

can you unlock it and use it on AT&T LTE? I am guessing not but I haven't seen much about this tablet so figured I would ask.

No, different carrier types, att is gsm while Verizon is CDMA.
While vzw does use some gsm for their lte it is not the same frequency so it will not work.
Sorry mate
I believe the xyboard has the same chipset as the Bionic so in theory the surprisingly easy hack to use the Bionic on gsm (US AND global) networks could likely work.
**THIS IS A SERIOUS PHONE MOD. NO ONE BUT YOU IS RESPONSIBLE IF YOU USE THE FOLLOWING**
Quick search came up with the following thread (says TMo) which someone acknowledges two posts below OP that it works on ATT:

The Droid Xyboard has both GSM and CDMA radios.
But GSM will only work on Non-American carriers, its blocked for AT&T and T-Mobile (I tried - didn't work).
Hypothetically speaking though, even if it did work on AT&T it would still not run on AT&T's LTE (only HSPA+) because it doesn't have the LTE frequencies.

Here's a thing, after set apn setting on the phone i just only get edge speed(2g), i need someone helps me to figure out how to get the 3g/4g speed on this phone or give me a right apn setting for this. i really appreciated. thanks very much!

It's not a worst thing though. I got this one for only 100$ off craiglist and it works just fine. It just does not work right with a data, remind me of few years back when 2g was a fastest data service lol. Thanks again for let me know this issue.
AT&T runs on GSM band while Verizon runs on a CDMA network. I'm surprised your SIM even works. What other said is correct though, you are restricted to the slow 2G Edge speeds.

Well the S3 is a World phone, hence it comes with GSM bands too! if you hit Europe or Asia you will get 3G

Right it does. But they use different bands in other countries. Our phone isn't capable of using any and all bands. Only certain ones. If somehow these bands were unlocked, then you could get 3g here.
